Description
The present invention relates to a curtain wall, and more particularly, to a curtain wall capable of precisely fastening a screw for fixing a glass panel to a center of a joining site of an aluminum structural member, thereby preventing rain water leakage and deterioration of appearance, Moon < / RTI >
In recent modern architectural style, curtain walls (windows) are used to block the rain and wind from the outside, to block noise and heat, and to prevent the pillars and beams from being exposed to the outside. curtain wall) method is attracting much popularity.
A curtain wall is a name attached to a building because it acts only as a curtain that divides a space in a structure that supports a vertical load applied to a building and a horizontal load caused by a wind or an earthquake by only a frame of a main structure of a building and a frame of a beam, It is also called the "strength partition wall". As the outer wall panel for curtain wall, a glass panel which is a typical exterior material is mostly used, and in order to prevent heat loss, double glass or heat ray absorbing glass is mainly used.
The curtain wall is used to block rain or wind from the outside and to block noise and heat, and the column and the beam are not exposed to the outside, and the wall using glass or the like has a large function as the exterior. Especially, it is widely used for high-rise or super-high-rise construction, and it is difficult to assemble scaffolding outside the building with height of 100m or more.
The basic structure of such a curtain wall is composed of a glass panel and a structural material such as a mullion and a transom of steel or aluminum alloy for fixing the glass panel. In addition, since the weight of the glass panel is very heavy, the strength and supporting force of the structural member supporting the glass panel and the supporting member for fixing the glass panel to the structural member are very important.
Patent Document 1 of the following prior art document shows a representative example of a steel curtain wall. That is, Patent Document 1 discloses a steel curtain wall in which a wall of a building is formed of a two-layer glass panel, a steel frame and a bracket of a rectangular cross-section are provided on the inside / outside of the horizontal and vertical connection portions of the double- And is screwed to the steel frame to join the neighboring multi-layer glass panels. Particularly, a dovetail groove is formed in the center of the fixing plate in front of the steel frame in the longitudinal direction, and an á-shaped wedge piece is inserted in the dovetail groove. An inner gasket is provided on both side fixing plates of the dovetail groove, An outer gasket corresponding to the gasket is provided so that the edge of the multilayer glass is abutted between the inner gasket and the outer gasket so that the washer bolt is screwed to the wedge piece inserted into the dovetail groove of the steel frame from the outside of the bracket. The structure of such a conventional steel curtain wall may also be applied to an aluminum curtain wall. However, in such a structure of the curtain wall, it is difficult to accurately fasten a fixing member such as a screw for fixing the glass panel to the center of the joint portion of the frame (i.e., aluminum structural member). Therefore, there is a high possibility that the fixing member for fixing the glass panel is warped in a distorted state at the center portion of the aluminum structural member. As a result, a clearance is generated in the fastening portion, making it difficult to join the outer cover, rainwater may permeate through the gap, and the aesthetic appearance may be damaged. Further, since there is no means for preventing the inflow of cool air between the glass panels, there is a problem that the heat insulating performance is lowered in winter and the rainwater blocking effect is also lowered.
On the other hand, Patent Document 2 discloses an aluminum insulating curtain wall having a structure in which a glass panel is fixed by using a connecting member to an aluminum fixing frame (that is, an aluminum structural member) as shown in Fig. However, since the connecting member is coupled to the aluminum fixing frame by the convex-concave method by the protruding portion and the groove portion, it is difficult to ensure a stable installation state of the glass panel because the bonding strength is reduced. It is also possible to form a predetermined space through the connecting member on the connecting member and to form a predetermined space between the aluminum fixing frame and the cover member on both sides of the connecting member to prevent heat exchange and ensure the heat insulating performance However, it is difficult to expect the heat insulating performance merely by forming the space portion.
In the conventional curtain wall shown in Patent Document 1, it is not easy for the operator to accurately fasten the fixing member for fixing the glass panel to the center portion of the opposing face of the aluminum structural member, so that the fixing member for fixing the glass panel is fixed at the center portion of the aluminum structural member There is a high possibility that the screw is screwed in a state of being bent. As a result, a clearance is generated in the fastening portion, making it difficult to join the outer cover, rainwater may permeate through the gap, and the aesthetic appearance may be damaged. In addition, since means for preventing the inflow of cool air between the glass panels is not provided, not only the heat insulating performance is deteriorated but also the rain water shielding effect is deteriorated. In the aluminum curtain wall as in Patent Document 2, the glass panel is fixed to the aluminum fixing frame by the connecting member which is coupled by the convex-concave method. However, this method has a problem that the bonding strength is low and the glass panel can not be stably installed In order to secure the heat insulation performance through the space formed between the inside of the connecting member and the both sides of the connecting member, there is a problem that the heat insulating performance can not be expected with such a space only.
The present invention has been developed in order to solve such a conventional problem, and it is an object of the present invention to provide a fixing device for fixing a glass panel accurately and easily to a center of a joining portion of an aluminum structural member, The object of the present invention is to provide a joining structure of an aluminum curtain wall.
According to an aspect of the present invention, there is provided a gasket comprising a first gasket provided between opposed glass panels and a front portion of an aluminum structural member on which the glass panels are installed, Wherein a glass panel fixing screw is attached to a joining portion provided on a front portion of the aluminum structural member from an outer side of the inner cap in a state in which a second gasket is provided on the outer side of the second gasket, The joining portion provided at the front portion of the aluminum structural member is embedded and is seated on the front portion of the aluminum structural member while being fitted to the engagement portion of the inclined engagement type, A wedge groove facing the center of the wedge groove is provided, The second gasket is interposed between the glass panels facing each other between the second gasket and the heat insulating material. The second gasket is coupled to the binding groove of the heat insulating material so as to block the cool air and moisture flowing between the second gasket and the glass panels, And a third gasket having a V-notch groove formed in a straight line with the wedge groove of the heat insulating material is provided at a site where the screw for joining is joined.
In the present invention, a locking protrusion may be formed in the coupling groove of the heat insulating material, and the third gasket may be provided with a locking protrusion such that the third gasket is not detached from the coupling groove.
In the present invention, the third gasket may be provided with a closed loop type shock absorber positioned between the glass panel and the heat insulating material.
In the present invention, the third gasket is provided with a downward inclination and a downward inclination between the glass panel and the second gasket at the lower side of the second gasket to induce the moisture penetrated through the upper side gap of the glass panels and the second gasket to be discharged to the outside, A drain guide portion extending vertically downward can be formed.
In the aluminum curtain wall connecting structure according to the present invention having the above-described structure, the grooves for guiding the screws are formed at the joint portion between the third gasket, the heat insulating material and the aluminum structural member, so that the screw for fixing the glass panel is warped So that it can be accurately coupled to the center. Therefore, the present invention can completely solve the problems such as difficulty in joining of the outer cover, damage to the outer appearance, infiltration of rainwater due to the gap, and the like, which may occur when the glass panel fixing screw is engaged in a distorted state.
In addition, since the heat insulating material is provided between the glass panel and the aluminum structural member, the heat insulating performance is improved as compared with the prior art, and the third gasket is installed between the glass panels to block the cold air that can flow into the glass panels It is possible to obtain an effect that the heat insulating performance is extremely excellent. Further, the third gasket is provided with a drain guide portion for guiding rainwater or the like introduced into the space between the second gasket and the glass panel to be discharged to the outside as well as for blocking cold air, thereby effectively eliminating inflow of rainwater into the aluminum structural material side.
